Certain COVID-19 Vaccines Linked to Elevated Risk of Guillain-Barré Syndrome

As the rate of vaccination increases so has the incidence of GBS—particularly after viral vector-based vaccines such as AstraZeneca.

As the vaccination rate continues to rise, an increasing number of side effects are being reported. Research indicates that COVID-19 viral vector-based vaccines increase the risk of Guillain-Barré syndrome (GBS) by three to four times compared to mRNA-based vaccines.

The Link Between Vaccines and Guillain-Barré Syndrome Risk 

Increasing evidence suggests an association between COVID-19 vaccines and Guillain-Barré Syndrome. One study revealed an increase in GBS cases within 42 days of receiving the first dose of the AstraZeneca vaccine. The researchers suggest a potential link between the AstraZeneca vaccine and the increased risk of GBS.
In March, a prospective surveillance study published in Scientific Reports indicated that out of 38,828,691 doses of COVID-19 vaccine administered in Gyeonggi Province, South Korea, between February 2021 and March 2022, 105,409 adverse events were reported, including 55 cases of GBS.
